FREDERICK ALEXANDER ALLEN EVANS, OF LONDON. ENGLAND,

VAPOR-LIGHTER.

To all whom it may concern Be it known that T, F REDERICK ALEXANDERALLEN EvANs, a subject of the King of Great Britain. residing in London,England, have invented certain new and useful Improvements inVapor-Lighters, of which the following is a specification.

In an appliance, herein called a vapor lighter, for producing a flame bycausing sparks generated by friction to impinge on a wick saturated withpetrol or like fuel, ignition in a current of air is more certain andthe flame less liable to extinction, when the sparks are generatedwithin a chamber which also contains the wick and is closed save for theopening through which access is had to the flame.

This chamber should be separate from that containing the fuel and forthis purpose the chamber has been formed by a diaphragm which is eithera transverse parti tion in the tube constituting the body of thelighter, or the closed end of a second tube slid into the body tube; ineach case the material saturated with petrol is on one side of thediaphragm through which the wick extends.

It is to this particular form of vapor lighter having the sparkgenerator and wick within a chamber formed by a diaphragm that thepresent invention relates.

Hitherto the ignition in this form has been by means of relative slidingmovement between the scraper and the so-called flint, the inner tubebeing slid into the outer tube to produce the sparks.

By the present invention the well known friction wheel turning on a pinis adapted as the scraper by mounting the pin in the plate that closesthe body tube or in lugs on the side of this tube, the wheel turning inaslot so that it extends into the tube to abrade the flint mountedtherein.

I have shown in the accompanying drawings Figures 1 and 2 axial sectionsof two vapor lighters each having an ignition chamber formed by adiaphragm and a wheel scraper mounted in accordance with the invention.

Referring to Fig. 1, the vapor lighter comprises an inner tube a fittingclosely in an outer tube 5, so as to turn therein. The outer end of theinnertube has a milled head 0 by which it can be readily turned to bringinto register with each other the lateral opening d in each tube, thisbeing the po Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed August 12, 1919. Serial No. 317,052.

sition shown in Fig. 1. By turning the tube a through a suitable angle,say one of 90, the opening in the inner tube becomes wholly out ofregister with that in the outer tube and the chamber 6, formed in theouter end of the inner tube by the diaphragm f, is closed. The part ofthe tube a on the other side of this diaphragm is packed with absorbentmaterial f/ and the wick tube It extends'through the diaphragm, the wickbeing embedded at its inner end in the absorbent material.

According to this invention the friction Wheel 11 is mounted to turn ona pin carried in the head 0 and its milled periphery bears aga nst theusual flint. 70 mounted within the tube a and urged against the wheel bya spring Z adjustable by a screw m, in the known manner.

Normally the relative angular position of the tubes (1 and Z) is that inwhich the openings cl are closed. For use the inner tube is turned intothe position shown, the movement being governed by one end of a notch aat the bottom of tube a, engaging with a stop 7) on the tube 6. Thewheel is then rotated by the finger, as usual, whereby sparks aregenerated and ignite the wick. To saturate the absorbent material, tubea may be withdrawn from tube 6 and its open end immersed in petrol.

In Fig. 2 the absorbent material is contained in a tube a closed at bothends and pushed into the outer tube Z), the wick tube 72. extendingthrough the inner end of this tube o The chamber 6 is formed in theouter tube 6 between the closed end of tube a and the hinged lid n. Thefriction wheel 2' turns on a pin carried by lugs on the outer tube 6 andthe flint is extends through the end of a recess 0 in the outer tube; itis subject to the pressure of spring Z, adjustable by turning screw 712.To saturate the absorbent material the tube a is withdrawn and immersedin petrol which enters the tube through an aperture 72.

Having thus described the nature of the said invention and the bestmeans I know of carrying the same into practical effect, I claim 1. Avapor lighter comprising a tube, a diaphragm in the said tubesubdividing it into a wick chamber and a fuel chamber, a wall of theWick chamber having a slot, a friction wheel mounted for rotation insaid slot, and a fiint contained within the said Wick chamber, the saidflint and wheel being in operative contact with each other Within theWick chamber.

2. A vapor lighter comprising an inner tube, a diaphragm in the saidtube subdividing it into a wick chamber and a fuel chamber, an outertube closed at one end into which the inner tube fits so as to turntherein, said inner tube having a milled head 10 and a pin traversingthe said slot. a friction wheel mountedto turn on the said pin as inaxis and having a diametrical cross sec- :1011 of SllbSHlIlUliiY thesame area as the ength or the slot. and a flint mounted in the said wickchamber in operative contact ith the friction Wheel.

In BBSEllIlOIlV whereof I have signed my name to this specification.
